The Unguarded Hour is a 1925 American silent comedy-drama film directed by Lambert Hillyer and starring Milton Sills, Doris Kenyon, and Claude King.

[1] The film's sets were designed by the art director Milton Menasco.

[2] As described in a review in a film magazine,[3] Bryce Gilbert (King), business man, shows his daughter Virginia (Kenyon) the folly of an intended elopement with a youth.

She goes to Italy and meets Duke Andrea d'Arona (Sills), a young and handsome man, who is puzzled by her jazzy American ways and doubts her character.

The sister kills herself and the tragedy brings the duke and the young American woman to an understanding of their love.
